SWIG (Simplified Wrapper and Interface Generator) Version: 4.0.1 (21 Aug 2019) Tagline: SWIG is a compiler that integrates C and C++ with languages including Perl, Python, Tcl, Ruby, PHP, Java, C#, D, Go, Lua, Octave, R, Scheme (Guile, MzScheme/Racket), Scilab, Ocaml. SWIG can also export its parse tree into XML. SWIG reads annotated C/C++ header files and creates wrapper code (glue code) in order to make the corresponding C/C++ libraries available to the listed languages, or to extend C/C++ programs with a scripting language. Up-to-date SWIG related information can be found at http://www.swig.org A SWIG FAQ and other hints can be found on the SWIG Wiki: https://github.com/swig/swig/wiki License ======= Please see the LICENSE file for details of the SWIG license. For further insight into the license including the license of SWIG's output code, please visit http://www.swig.org/legal.html Release Notes ============= Please see the CHANGES.current file for a detailed list of bug fixes and new features for the current release. The CHANGES file contains bug fixes and new features for older versions. A summary of changes in each release can be found in the RELEASENOTES file. Documentation ============= The Doc/Manual directory contains the most recent set of updated documentation for this release. The documentation is available in three different formats, each of which contains identical content. These format are, pdf (Doc/Manual/SWIGDocumentation.pdf), single page html (Doc/Manual/SWIGDocumentation.html) or multiple page html (other files in Doc/Manual). Please select your chosen format and copy/install to wherever takes your fancy. There is some technical developer documentation available in the Doc/Devel subdirectory. This is not necessarily up-to-date, but it has some information on SWIG internals. Documentation is also online at http://www.swig.org/doc.html. Backwards Compatibility ======================= The developers strive their best to preserve backwards compatibility between releases, but this is not always possible as the overriding aim is to provide the best wrapping experience. Where backwards compatibility is known to be broken, it is clearly marked as an incompatibility in the CHANGES and CHANGES.current files. See the documentation for details of the SWIG_VERSION preprocessor symbol if you have backward compatibility issues and need to use more than one version of SWIG. Installation ============ Please read the Doc/Manual/Preface.html#Preface_installation for full installation instructions for Windows, Unix and Mac OS X using the release tarball/zip file. The INSTALL file has generic build and installation instructions for Unix users. Users wishing to build and install code from Github should visit http://swig.org/svn.html to obtain the more detailed instructions required for building code obtained from Github - extra steps are required compared to building from the release tarball. Testing ======= The typical 'make -k check' can be performed on Unix operating systems. Please read Doc/Manual/Preface.html#Preface_testing for details. Examples ======== The Examples directory contains a variety of examples of using SWIG and it has some browsable documentation. Simply point your browser to the file "Example/index.html". The Examples directory also includes Visual C++ project 6 (.dsp) files for building some of the examples on Windows. Later versions of Visual Studio will convert these old style project files into a current solution file. Known Issues ============ There are minor known bugs, details of which are in the bug tracker, see http://www.swig.org/bugs.html. Troubleshooting =============== In order to operate correctly, SWIG relies upon a set of library files. If after building SWIG, you get error messages like this, $ swig foo.i :1. Unable to find 'swig.swg' :3. Unable to find 'tcl8.swg' it means that SWIG has either been incorrectly configured or installed. To fix this: 1. Make sure you remembered to do a 'make install' and that the installation actually worked. Make sure you have write permission on the install directory. 2. If that doesn't work, type 'swig -swiglib' to find out where SWIG thinks its library is located. 3. If the location is not where you expect, perhaps you supplied a bad option to configure. Use ./configure --prefix=pathname to set the SWIG install location. Also, make sure you don't include a shell escape character such as ~ when you specify the path. 4. The SWIG library can be changed by setting the SWIG_LIB environment variable. However, you really shouldn't have to do this. If you are having other troubles, you might look at the SWIG Wiki at https://github.com/swig/swig/wiki. Participate! ============ Please report any errors and submit patches (if possible)! We only have access to a limited variety of hardware (Linux, Solaris, OS-X, and Windows). All contributions help. If you would like to join the SWIG development team or contribute a language module to the distribution, please contact the swig-devel mailing list, details at http://www.swig.org/mail.html. -- The SWIG Maintainers Below are the changes for the current release.

The following usage (using std::vector) would fail when using -builtin: %include %include %inline %{ struct X {}; %} %template(VectorX) std::vector; %template(VectorInt) std::vector; %inline %{ using namespace std; string VectorOverload(vector v); string VectorOverload(vector v); %} The following would incorrectly fail: s = VectorOverload([1, 2, 3]) With: Traceback (most recent call last): File "runme3.py", line 20, in ret = VectorOverload([1, 2, 3]) TypeError: Wrong number or type of arguments for overloaded function 'VectorOverload'. Possible C/C++ prototypes are: VectorOverload(std::vector< Number,std::allocator< Number > >) VectorOverload(std::vector< int,std::allocator< int > >) The problem was due to some error handling that was not cleared during typehecking. In this case an error was not cleared when the elements in the list failed the typecheck for converting to X. Only occurs in Python 3+. In some combinations of overloaded methods, the following type of error message would occur: RuntimeError: in sequence element 0 The above exception was the direct cause of the following exception: Traceback (most recent call last): File "runme3.py", line 23, in check(VectorOverload(v), "vector") SystemError: returned a result with an error set 2019-08-01: wsfulton #1602 Fix regression in 4.0.0 where a template function containing a parameter with the same name as the function name led to the parameter name used in the target language being incorrectly modified. 2019-07-29: wsfulton Remove all generated files on error. Previously generated files were not removed, potentially breaking Makefiles using file dependencies, especially when -Werror (warnings as errors) was used. 2019-07-23: smithx [C#] #1530 #1532 Fix marshalling of std::wstring to C#. 2019-07-18: gicmo [Python] #1587 Python 3.8 support - remove use of deprecated PyObject_GC_UnTrack. 2019-07-18: cher-nov [Python] #1573 Generated Python code uses consistent string quoting style - double quotes. 2019-07-16: geefr [C#] #616 #1576 Fix C# bool INPUT[], bool OUTPUT[], bool INOUT[] typemaps to marshall as 1-byte. 2019-07-12: vadz [C#, Java] #1568 #1583 Fix std::set<> typemaps for primitive types. 2019-07-12: vadz #1566 #1584 Regression in 4.0.0 - fix missing value for first item of enums with trailing comma. 2019-07-11: mcfarljm #1548 #1578 Fix segfault in Doxygen parser parsing empty lines in some commands like \code. 2019-07-09: IsaacPascual [C#, Java] #1570 Fix name of generated C#/Java classes for %interface macros in swiginterface.i when wrapping nested C++ classes. 2019-07-05: wsfulton [Python] #1547 Whitespace fixes in Doxygen translated comments into pydoc comments for Sphinx compatibility. 2019-06-28: wsfulton [MzScheme, OCaml] #1559 $arg and $input were incorrectly substituted in the argout typemap when two or more arguments were present. 2019-06-24: wsfulton [Python, Ruby] #1538 Remove the UnknownExceptionHandler class in order to be C++17 compliant as it uses std::unexpected_handler which was removed in C++17. This class was intended for director exception handling but was never used by SWIG and was never documented. *** POTENTIAL INCOMPATIBILITY *** 2019-06-06: bkotzz [Java] #1552 Improve performance in Java std::vector constructor wrapper that takes a native Java array as input. 2019-06-03: olly [Python] Fix regression in implicit_conv handling of tuples, introduced in SWIG 4.0.0.
